Summary

This update of xDSL brings an update to the version of mlir-opt that it is compatible with, we are now compatible with the version distributed with LLVM version 19.1.7. This will hopefully make it easier for users to use tools distributed with LLVM.

It also contains some updates to assembly-level dialects and CSL infrastructure.
